Layer Emitter other than Particular?

Hi everybody,

I'm tasked with the challenge of making a floating object "gallery" (for lack of better wording) within a 3D space. One filled with an array of images that I need to fly or venture through with more in the background. 

My idea is that I'd use some kind of emitter or something at least semi-procedual to create an array of these images, then just copy or multiple them within 3D camera depth so to create an illusion of a vast numbers of these images floating in a world. 

I know that Particular has a Layer Emitter that might possibly lend itself to this sort of situation. But I can't get anything in the Maxon bundle right now. So I'm trying to figure out what might be a good way to set up a number of nodes/nulls (like 12-24) or some randomized series and then multiply it in a 3D space for this effect.

Does anybody have any suggestions for what they might do in this situation?  I imagine I could randomize a number of nodes within a given space without too much troubleshooting, but getting a continuing random array of layers to populate on these nodes/nulls, that's what slowing me down.

Thanks for reading! 🙂
